Dark construction paper
Liquid glue like Elmer’s
Assorted seashells, sea glass and other found objects.
Cut a sheet of paper to fit inside the shoebox lid and glue in place. Using the glue bottle, draw a design on the paper. You can make flowers, a landscape, a funny face, whatever suits your fancy. Make sure you draw it in such a way that when you sprinkle it with sand, the design will still be evident. For instance, it could be the outline of a face, or mountains or the stems of flowers. Then, while the glue is still wet, sprinkle it with sand. Shake off the excess and fill in your design details with the beach objects.
